Aphasia is a condition that may present itself for a number of different medical reasons, and understanding the causes, signs, and symptoms may help a sufferer know when to seek medical attention. Aphasia is language disorder and a unique condition in that it causes the sufferer to have difficulty understanding language, speaking with others, and reading, but it doesn't mean the sufferer is not smart or has become less intelligent due to the condition. Aphasia also doesn't impact the way a person thinks; it is a language disorder rather than a sign of mental deficiency.When brain damage occurs and aphasia results, a person may also suffer from related conditions like dysphagia, which is a problem swallowing or dysarthria, which is a muscle weakness inside the mouth. People who suffer from migraines may experience transient aphasia, which is a temporary occurrence of the condition that may come and go as the sufferer experiences the symptoms of a migraine aura. Abnormally functioning neurons may cause the problem to arise during a migraine. According to the American Speech-Language-Hearing Association, aphasia is most commonly caused by a stroke, but brain damage of any type may cause it to occur.
